Description of the Related Art Conventionally, a shopping system has been known that enables a user to make a transaction such as a product or service through a web page provided from a web server or the like by connecting to a network such as the Internet using a terminal device such as a personal computer. ing.

In such a system, the number of stocks is generally displayed on a Web page that displays information on products or services to be traded.

For example, Patent Literature 1 discloses a method for displaying the number of stocks in a figure on a user terminal device.

Also, the number of stocks to be traded is usually registered in the database in association with each trade target. The information on the number of stocks registered in the database is updated to reflect the number of stocks that change from moment to moment according to the status of transactions. Therefore, every time the Web server receives a request for a Web page that displays the inventory quantity, it is necessary to inquire the database about the inventory quantity.

Japanese Patent Laid-Open No. 10-91711

However, in the conventional method described above, the database must be accessed every time it is necessary to display the number of stocks. Therefore, there is a problem that processing delay is caused by accessing this database.

In this regard, the method described in Patent Document 1 is the same. In other words, in this method, graphics are made at intervals of 10 seconds, but in order to generate a graphic image corresponding to a change in the number of stocks, it is necessary to access the database each time the image is generated.

The present invention has been made in view of the above points, and can reduce the processing load by reducing the number of times the inventory quantity is acquired when transmitting information such as a web page that displays the inventory quantity. An information transmission apparatus, an information transmission method, an information transmission processing program, and an information transmission system are provided.

In order to solve the above-mentioned problem, the invention according to claim 1 displays the received data on the screen and stores it in the storage means provided therein, and when the data to be received is already stored, the data is stored. An information transmitting device that transmits, via a network, page information indicating the number of stocks to a terminal device that acquires and displays the information from the storage unit, and a request receiving unit that receives a request transmitted from the terminal device; In addition, when a request indicating a request for a hypertext that constitutes the page information is received, the tag information includes location information indicating a location in the image data corresponding to the stock quantity, and includes tag information for displaying the image data.

Hereinafter, the best embodiment of the present invention will be described in detail with reference to the drawings. In addition, embodiment described below is embodiment at the time of applying this invention with respect to a shopping system.

[1. Overview of shopping system configuration and functions]
First, the structure and outline | summary function of the shopping system S which concern on this embodiment are demonstrated using FIG.1 and FIG.2.

FIG. 1 is a diagram illustrating an example of a schematic configuration of a shopping system S according to the present embodiment. FIG. 2 is a diagram illustrating a screen display example of the product detail page 200.

As illustrated in FIG. 1, the shopping system S includes a Web server 1 as an example of an information transmission device including a product database 100 as an example of a database, and a user terminal 4-k (k = 1, 1) as an example of a terminal device. 2... N).

In addition, the Web server 1 and the user terminal 4-k can exchange data with each other via the network NW, for example, using TCP / IP (Transmission Control Protocol / Internet Protocol) as a communication protocol. Yes. The network NW1 is constructed by, for example, the Internet, a dedicated communication line (for example, a CATV (CommunityCommunAntenna Television) line), a mobile communication network (including a base station, etc.), a gateway, and the like.

In the shopping system S having such a configuration, the Web server 1 is a server device installed to open a shopping site by a service provider that provides various services through the network NW.

Information such as the number of stocks of products sold and information related to the sale and sale of products are registered in the product database 100 constructed in the Web server 1.

Then, the Web server 1 accesses the product database 100 in response to a request from the user terminal 4-k, and performs processing for establishing the sale of the product between the seller and the user of the user terminal 4-k. To do.

The user terminal 4-k accesses the Web server 1, acquires a Web page, and displays it on the screen. Thereby, the user can purchase a product through the Web page.

The user terminal 4-k is, for example, a personal computer or PDA (Personal Digital Assistant) installed with a browser application such as Internet Explorer (trademark), or a program for browsing a Web page is installed in advance. Mobile phone etc. With such a program, the user terminal 4-k can receive various data (HTML (Hyper Text Markup Language) (an example of hypertext) configuring the web page, image data, etc.) received from the web server 1 when browsing the web page. ) Is stored in RAM (Random Access Memory), hard disk, etc. (an example of storage means), and the next time the user browses the same Web page, the saved data is acquired and displayed on the screen It will have.

The Web server 1 transmits a product detail page 200 (an example of page information) displaying detailed product information as shown in FIG. 2 to the user terminal 4-k. At this time, the Web server 1 transmits a product detail page 200 that displays the numerical characters of the product inventory in image data. In FIG. 2, reference numeral 201 denotes image data for displaying the inventory quantity (hereinafter referred to as “inventory quantity image data”).

Accordingly, the user terminal 4-k that has received the HTML data (hereinafter referred to as “HTML data for product details”) constituting the product detail page 200, the stock quantity image data indicating the stock quantity, and the like receives these data. save. Therefore, when it is necessary to display the stock quantity of the same product next time, the saved stock quantity image data is read out and displayed, so that it takes less time to display on the user terminal 4-k. There is. Further, since the number of times of receiving the stock quantity image data request is reduced on the Web server 1 side, it is not necessary to acquire the stock quantity information from the product database 100, and the processing load is reduced.

However, in this case, the number of items in stock will not be reflected in real time. However, in general, the user browses the details of the product, but the purpose is simply surfing the Internet or the user does not like the content of the product, and often the product is not purchased. Accordingly, since the importance of the inventory quantity at this stage is not so high, even if the inventory quantity displayed on the product detail page 200 deviates from the actual inventory quantity, it does not matter so much. However, at the stage where the user actually decides to purchase the product (for example, when the product is put in the cart in FIG. 2), there is an inconvenience if there is no stock for the number to be purchased. In this case, the Web server 1 Obtains information on the number of stocks from the database 100.

[2. Configuration and function of Web server]
Next, the configuration and function of the Web server 1 will be described with reference to FIGS.

FIG. 3 is a block diagram illustrating an example of a schematic configuration of the Web server 1 according to the present embodiment. FIG. 4 is a diagram showing an example of the content of the product detail HTML data.

The display unit 12 includes, for example, a CRT (Cathode Ray Tube) display, a liquid crystal display, and the like, and displays information such as characters and images. The communication unit 13 is connected to a network NW or the like, and controls the communication state with other server devices, user terminals 4-k, and the like. For example, the drive unit 14 reads data from a disk DK such as a flexible disk, a CD (Compact Disc), a DVD (Digital Versatile Disc), and the like, and records data on the disc DK. The storage unit 15 is configured by, for example, a hard disk drive or the like, and stores various programs, data, and the like. The input / output interface unit 16 performs interface processing between the operation units 11 to 15 and the system control unit 20. The system control unit 20 includes a CPU (Central Processing Unit) 17, a ROM (Read Only Memory) 18, a RAM 19, and the like.

The product database 100 is constructed in the storage unit 15. In the product database 100, the name of the product, the explanatory information indicating the detailed description, the stock quantity information indicating the stock quantity of the product, etc. are associated with the product ID (Identification) for identifying the product for each product. It is registered.

Also, the storage unit 15 stores various types of HTML data (including product detail HTML data), image data, audio data, text data, and the like that constitute the Web page of the shopping site.

Furthermore, in addition to a predetermined operating system, the storage unit 15 uses the HTTP (Hyper Text Transfer Protocol) protocol and stores it in the storage unit 15 in response to a request transmitted from the user terminal 4-k or the like. A WWW (World Wide Web) server program for transmitting a web page to the user terminal 4-k or the like based on various data is stored.

Furthermore, the Web server 1 stores a shopping processing program for performing processing related to sales, purchases, etc. of products on a shopping site.

Various programs may be acquired from other server devices via the network NW, for example, or may be recorded on a disk DK such as a CD-ROM and read via the drive unit 14. Anyway.

The system control unit 20 of the Web server 1 constitutes an example of a request reception unit, a hypertext transmission unit, a stock quantity information acquisition unit, an image data generation unit, an image data transmission unit, and the like.

The system control unit 20 of the Web server 1 controls each unit of the Web server 1 by the CPU 17 reading and executing various programs stored in the ROM 18 and the storage unit 15 and functions as each unit described above. It is like that. The function as each means will be described.

The system control unit 20 as a request receiving means receives various HTTP requests transmitted from the user terminal 4-k.

Further, the system control unit 20 as the hypertext transmission means receives an HTTP request (an example of a request indicating a hypertext request) in which the URL (Uniform Resource Locator) of the product detail HTML data is described in the header. Acquires the product detail HTML data indicated by the URL from the database 100 and transmits the HTML data to the user terminal 4-k.

This product detail HTML data is described as shown in FIG. Reference numeral 151 in FIG. 4 is an IMG tag (an example of tag information). This IMG tag corresponds to the display of the stock quantity (stock quantity image data) indicated by the reference numeral 201 in FIG. As the src attribute of the IMG tag, the URL (an example of location information) of the inventory quantity image data corresponding to the product whose details are to be displayed is described. By including the product ID or the like in this URL, it is possible to determine which product stock number should be displayed.

When receiving an HTTP request (an example of a request including location information) in which the URL of the inventory quantity image data is described in the header, the system control unit 20 as the inventory quantity information acquisition unit selects a product corresponding to the URL. The inventory number information of this product is specified and acquired from the database 100.

Further, the system control unit 20 as image data generating means displays the numerical value of the inventory quantity indicated by the acquired inventory information in characters (for example, reference numeral 201 in FIG. 2) to generate inventory quantity image data. .

Further, the system control unit 20 as the image data transmitting means transmits the generated inventory quantity image data to the user terminal 4-k that requested it.

A server device specializing in the above may be provided separately, and the Web server 1 may exchange data with respect to the product database 100 via the server device. Also, a plurality of web servers may be provided so that all the web servers access one product database 100.

[3. Operation of shopping system]
Next, the operation of the shopping system S will be described with reference to FIG.

FIG. 5 is a flowchart showing a processing example of the shopping system S according to the present embodiment.

First, the user accesses the shopping site by operating the user terminal 4-k, and searches for a product by keyword search or the like. When a desired product is selected from the search result list page from the Web server 1, as shown in FIG. 5, the user terminal 4-k determines whether or not the product detail HTML data of the selected product is cached. Is determined (step S1). At this time, if the product detail HTML data is cached (step S1: YES), the user terminal 4-k acquires the product detail HTML data from the cache (step S4), and proceeds to step S5. To do.

On the other hand, when the product detail HTML data is not cached (step S1: NO), the user terminal 4-k transmits a product detail HTML data request to the Web server 1 (step S2). Specifically, the user terminal 4-k transmits a GED method in which the URL of the link of the product selected by the user is set as the request URL.

The system control unit 20 of the Web server 1 that has received the product detail HTML data request (step S21) transmits the product detail HTML data corresponding to the set request URL to the user terminal 4-k (step S22). .

When the user terminal 4-k receives the product detail HTML data (step S3) or acquires the product detail HTML data from the cache (step S4), the user terminal 4-k receives or acquires the product detail HTML. The data is analyzed and the data is displayed on the screen (step S5).

At this time, since the user terminal 4-k detects the IMG tag for displaying the inventory quantity image data, it determines whether or not the inventory quantity image data is cached (step S6). At this time, if the inventory quantity image data is cached (step S6: YES), the user terminal 4-k acquires the inventory quantity image data from the cache (step S9), and proceeds to step S10.

On the other hand, if the inventory quantity image data is not cached (step S6: NO), the user terminal 4-k transmits an inventory quantity image data request to the Web server 1 (step S7). Specifically, the user terminal 4-k transmits a GED method in which the URL set in the src attribute of the IMG tag is set as the request URL.

The system control unit 20 of the Web server 1 that has received the inventory quantity image data request (Step S23) acquires inventory quantity information corresponding to the set request URL from the product database 100 (Step S24).

Next, the system control unit 20 generates inventory quantity image data for displaying the inventory quantity indicated by the acquired inventory quantity information in characters (step S25), and transmits this inventory quantity image data to the user terminal 4-k (step S25). S26).

When the user terminal 4-k receives the inventory quantity image data (step S8) or acquires the inventory quantity image data from the cache (step S9), the user terminal 4-k displays the received or acquired inventory quantity image data on the screen. (Step S10). In this way, the product detail page 200 is displayed as shown in FIG.

In FIG. 5, the user terminal 4-k checks whether or not the stock quantity image data is cached even when the product detail HTML data is cached (step S1: YES). (Step S6). This is because although the product detail HTML data is cached, the stock quantity image data is not cached. For example, since the expiration date can be set for the inventory quantity image data on the Web server 1 side, when the expiration date of the inventory quantity image data cached in the user terminal 4-k expires, the browser application specification This is because the stock quantity image data may be deleted from the cache.

On the other hand, on the Web server 1 side, the expiration date of the stock quantity image data may be set. This is because the frequency and possibility of updating the inventory quantity is higher than the product detail HTML data itself, so the inventory quantity displayed by the user terminal 4-k (the inventory quantity image data to be cached) is also appropriate. This is because it is desirable to update the frequency. For example, the expiration date of the inventory quantity image data is set 10 minutes after the generation of the data, and the expiration date of the product detail HTML data itself is the same as the expiration date set by the browser application (for example, 20 days after the cache time). As a result, it is possible to update the inventory quantity more accurately while reducing the load on the Web server 1. Of course, it is possible to set the expiration date of the product detail HTML data on the Web server 1 side.

In order to set the expiration date on the Web server 1 side, when the system control unit 20 transmits the stock quantity image data to the user terminal 4-k, the stock quantity image is displayed in the Expires header or the Cache-Control header as an HTTP header of the response. The date and time when the data is no longer valid may be set. On the other hand, while the cached image data is valid, the user terminal 4-k acquires the image data from the cache and displays it on the screen. Even if the image data is deleted from the cache or not deleted, the contents of the cache are updated by receiving the image data from the Web server 1 again.

As described above, according to the present embodiment, when the system control unit 20 of the Web server 1 receives the product detail HTML data request, the URL of the stock quantity image data that displays the stock quantity of the corresponding product in characters. The product detail HTML data including the IMG tag set as the src attribute is transmitted to the user terminal 4-k. The user terminal 4-k displays the stock quantity characters as an image based on the received IMG tag of the product detail HTML data. When the stock quantity is displayed for the first time, the stock quantity image data is not cached, so the user terminal 4-k transmits an image data request to the Web server 1. In response to this, the system control unit 20 of the Web server 1 acquires inventory quantity information from the product database 100, generates inventory quantity image data, and transmits it to the user terminal 4-k. The user terminal 4-k that has received the stock quantity image data displays the stock quantity image data on the screen and caches it. Once the inventory quantity image data is cached, the user terminal 4-k displays the cached inventory quantity image data on the screen without transmitting a request to the Web server 1. Then, since the system control unit 20 of the Web server 1 does not receive the inventory quantity image data request, it is not necessary to acquire inventory quantity information from the database. Therefore, it is possible to reduce the number of times of acquiring the inventory quantity information from the database.

In the above description, when the product details HTML data is cached, the user terminal 4-k uses the cached data as it is without checking the last update date. Depending on the specifications and settings of the browser application or the like, the Web server 1 may be inquired about the last update date, and if these data are updated, a request may be made to the Web server 1. Generally, when data once displayed is displayed again in the same session as that time, it is often set not to check the last update date.

In addition, depending on the settings of the browser application and the like, the user terminal 4-k deletes the inventory number image data from the cache after a certain period of time has elapsed since receiving the inventory number image data. Is displayed, the inventory quantity image data is received from the Web server 1 again.
